In terms of cancellation, United Airlines provides different cancellation options according to the types of tickets purchased. A passenger who has booked a refundable ticket can cancel any time without penalty, receiving a full refund. A non-refundable ticket becomes a bit more of a muddle, but financial losses could still be minimized other ways.
One of the most convenient aspects of the United Airlines Cancellation Policy is the 24-hour flexible booking option. If your flight is canceled within 24 hours of booking and you are departing at least one week later, you qualify for a full refund, without regard to fare type.
In the event of non-refundable tickets, United Airlines provide flight credits rather than cash refunds. If the ticket is canceled after the 24-hour period, the canceled ticket is converted into travel credits for a customer to use at a later date.
